A large number of phased array antenna with low grating lobes using partially driven technique
In this paper, a phased array antenna which has a large number of element antenna and low grating lobes is described. The element antenna has a conical shaped radiation pattern which is suitable for a mobile satellite communications. To reduce a number of phase shifter, partially driven array technique which is one kind of thinned array is employed. The beam scanning characteristics of 243-element array antenna are investigated computationally.
